Abstract
In reality, nanotechnology is transforming many areas of human life. It is a crucial component of many applications, including those that deal with environmental pollution, nanomedicine and health, water purification, and waste treatment. Nanotechnology has a significant role in the economy of many countries. The global nanotechnology market is expected to be more than $ 125 billion in 2024. In fact, this expectation is not fixed, but it can be changed anytime. As known, COVID-19 emerged in 2019 and 2020, and some companies, banks, etc. have gone bankrupt. Due to the COVID-19 pandemic, plans and estimates have obviously changed. As reported, there are four generations of nanotechnology. The first generation is concerned with improved nanostructures, and the second generation is concerned with the application of nanostructures, such as drug delivery. The third and fourth generation are concerned with the further integration of nanomaterials applications, such as the use of nanobots in drug delivery.
Keywords: Environment and nanotechnology, Future of Nanotechnology, Nanoarts, Nanomedicine, Nanotechnology and Economy, Water purification.
